Are there variants of this concept where one can set constraints over the locations of certain key vertices, such as remaining certain vertex locations fixed?
e.g. Let's say someone is modeling something with sharp points, such as a nail. I imagine running a standard subdivision algorithm would eventually smooth the nail's body, which is desired, but would also smooth out the nail's tip.
Are there variants where one can smooth most of the object but keep certain points or regions (not just edges) sharp?

I would assume that you could simply make it so that the "sharp" corner is actually a really small square or some other un-noticable figure, and you could use that to your advantage to create a tip that stays sharp. After all, at some point the size of the tip isn't visible and you will have the same nail shape.
